Troubleshooting common Evaporative cooling issues / faults:

  • Check time delay, usually can take up to 10 minutes to start. Cooler filling up the tank with water, or a pre-wetting the filter pads

  • Check that the fan operates, and the air is coming out from the vents.

Evaporative cooling common issues and problems


When the cooling is first turned ON, there will generally be a delay before the cool air is delivered from the duct outlets. The delay will vary depending on the cooler's brand/model, but this doesn’t mean the cooler is not operating. Most coolers have pre-programmed delay times to fill up the Cooler’s tank with water and/or Pre-wet the filter pads. The entire process can take up to 10 minutes before cool air is expected from the duct outlets.

Shut down

Many modern cooling units are fitted with a sump dump valve, there is also a delay in emptying the water from the Cooler’s tank for a period after the unit has turned OFF at the end of use. Some models have an additional pre-programmed tank wash cycle. This washes the tank with clean water at the end of use.

If you’ve noticed that it takes the Cooler too long to Startup, or it’s continuously leaking water outside of the operating cycle - it might be there is a problem, and it’s a good idea to get it checked by a Licenced Technician.

Evaporative cooling common issues and problems

Q. How often should the cooler be serviced?
A. All manufacturers recommend servicing the cooler every 2-3 years to ensure it operates at peak efficiency. Maintenance is recommended to be performed before the summer season to keep cool and comfortable through the summer months.

Q. The air smells a little different. Why?
A. The brand-new cooling pads can give off a mild odour while settling in. However, if the cooler is a few years old, it may be indicating that the unit needs a thorough cleaning and check.

Q. How much water does my evaporative cooler use?
A. The amount of water an evaporative cooler uses depends on the cooler's pads' evaporation rate. On a hot day, the cooler may refill every half an hour.

Q. How many doors and windows should I have open?
A. Evaporative cooling relies on doors and windows being open, so you need to provide the minimum required airflow relief area. Refer to the owner’s manual for exact numbers. The Rule of thumb is at least one door and window must be open.

Q. Why is there condensation and moisture on my tiles and furniture?
A. If condensate is forming on a hard surface while the evaporative cooler is ON, first of all, make sure a sufficient number of doors and windows are open. Check that the vents are directed across the room and not towards the floor. Also, ensure the unit and filter pads are clean and free of debris.

Q. Is Evaporative cooling effective? How cool is cool?
A. The degree of cooling available from any air conditioning system, is dependent on the outside weather conditions. Evaporative Cooling works best on hot, dry days. If the unit is clean and functioning correctly, you should expect a temperature difference of at least 10 Degrees Celsius.

Q. Should water be coming out of my evaporative cooler during operation?
A. Modern coolers shouldn’t leak any water during operation as they have an Auto Drain Valve fitted. Some models will complete a flush service approximately every 20 cycles. Also basic or older Cooler models have a “bleed-off” system installed and will discharge a small continuous flow from the drain outlet while the pump is ON.

    This man is one of the best tradies I have encountered.
    Polite, punctual and most of all is an expert at what he does at a very reasonable price.
    Last year he serviced my Brivis evap. cooler. He took before and after photos as I wasn't getting on the roof for an inspection haha. This was his idea and I'd never thought about it.
    He brought all the panels down for a good scrubbing. Other plummers have only hosed them down on the roof.
    All in all, a very thorough tradesman.
    This year Serge replaced my four vents in the house. They look terrific, and have a shiny finish for easy cleaning. He cleans up and takes all the rubbish with him
    I'll happily refer him to my friends with confidence.
    Thanks again Serge
